The device number is defined once to allow identification of different IC-Types by software.
The revision number may be utilized to distinguish different states of hardware. The content is divided in an upper
4-bit field reserved to define revisions corresponding to specific Software Releases.
The lowest 4-bit field is utilized to identify the actual mask set.
Both (SWR and MSR) will start with 0000b and are increased by 1 every time a corresponding modification of the
hardware is introduced.
